Custom Http Handler to redirect to different page in ASP.Net

Hi mukesh1,

Check this example. Now please take its reference and correct your code.

First create class handler and inherit it with the interface IHttpHandler.

C#

using System;
using System.Web;

/// <summary>
/// Summary description for handler
/// </summary>
public class handler : IHttpHandler
{
    public handler()
    {
        //
	// TODO: Add constructor logic here
	//
    }

    public bool IsReusable
    {
        get { throw new NotImplementedException(); }
    }

    public void ProcessRequest(HttpContext context)
    {
        context.Response.Redirect("users/newtask.htm");
    }
}

Now in code behind you need to check the extension from Request.Url in page load or in Global.asax file Session_Start event. If the url contains .aspx extension then call the handler class.

C#

string path = Request.Url.ToString();
if (path.Contains(".aspx"))
{
    handler handler = new handler();
    handler.ProcessRequest(HttpContext.Current);
}

For that you don't need handler.

Create a PageBaseClass.cs and inside it write code for Redirecting if the URL ends with .aspx.

Then inherit all pages with the PageBaseClass.

PageBaseClass

/// <summary>
/// Summary description for PageBaseClass
/// </summary>
public class PageBaseClass : System.Web.UI.Page
{
    protected void Page_PreInit(object sender, EventArgs e)
    {
        if (Request.Url.AbsolutePath.EndsWith(".aspx"))
        {
            //Redirect here.
        }
    }
}

Page

public partial class _Default : PageBaseClass
{
     protected void Page_Load(object sender, EventArgs e)
     {
     }
}
